Flyer clearer



FLYER CLEARER Filed Oct. 21, 1939 "Patented Apr. 23, 1940 VUNITED srA'rEs ATENT OFFICE Claims.

This invention relates to a flyer clearer, and

it is an object of the invention to provide a cleaner to be mounted upon a spindle of a roving frame for coaction with the associatedfiyer and in a manner whereby the cleaner is operated from the bobbin on the spindle by both the revolving power of the bobbin and the up and down traverse of the bobbin.

It is also an object of the present invention to provide means whereby the flyersof a roving frame may be cleaned of lint and other foreign materials which might otherwise cause bunches and unevenness in the slivers as the slivers are being twisted and wound upon the bobbin.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved flyer clearer whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth,

The novel features of my invention will hereinafter be. definitely claimed.

In order that my invention may be the better understood, I will now proceed to described the same with reference to the accompanying drawing, wherein:

Figure 1 is a fragmentary view of a textile machine having iiyer clearers constructed in accordance with an embodiment of my invention applied thereon;

Figure 2 is a view in perspective of one of the clearers unapplied. v 5 In the accompanying drawing, I denotes a conventional spindle comprised in a roving frame and upon which spindle is placed the usual bobbin 2. The spindle l and bobbin 2 are driven in a well known manner, the speed of the spindle 40 being constant while the bobbin 2 revolves at a variable speed. The bobbin 2 has up and down traverse on the spindle l in the usual manner by the table 3. Mounted upon the upper end of the spindle l for rotating therewith is a conven- 45 tional flyer F including the depending elongated arms 4 in parallelism with each other and with the spindle l and between which the bobbin 2 revolves. The bobbin 2 and the flyer F rotate in the same direction. The parts hereinbefore 50 referred to are well known and form no part of the present invention.

My improved clearer comprises an elongated member 5 provided with a central opening 6 whereby said member may be freely mounted up- 55 on the spindle i above the bobbin 2. This memweight to be constantly in contact with the upper TO I end of the bobbin 2, the member 5 willtraverse up and down the spindle I with the bobbin 2 thus materially increasing the efliciency of the vclear-. ing' device.

Suitably secured to each extremity of the mm- 1 her 5 and extending outwardly therefrom are the fibre brushes 1. These brushes are of a length to contact with the arms 4 of the fiyer as the member 5 rotates around the spindle l and traverses up and down thereon thus freeing the 20- arms 4 of lint or other foreign materials which may collect thereon.

It order that the upwardly and inwardly curved portions :1. of the arms 4 of the flyer may also be free of lint or other foreign materials thereon, the member 5 at opposite sides of its central opening 6 and in relatively close proximity thereto is provided with the upstanding elongated fibre brushes 8 which have the desired clearing or cleaning contact with said portions a of the arms 4.

It is to be particularly pointed out that the member 5 derives both its rotary and up and down movements from the bobbin 2.

Without the use of my improved clearer, as the carriage 3 rises and drops a certain amount of lint, dust and other foreign materials willvcollect on the fiyer F. As this foreignmaterial builds: up it will have a tendency, as by air and centrifugal force, to be loosened from the liver F and 40 be picked up and carried along by the sliver or roving through the liver F into the bobbin 2 or to other adjoining strands and bobbins. This causes bunchc's and unevenness in the fibre. With the use of my improved device such disadvantages are fully overcome.

From the foregoing description it is thought to beobvious that a fiver clearer constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. In combination with the associated spindle, bobbin and flyer of a roving frame, a cleaning device for the fiyer freely mounted upon the spindle, said cleaning device having rotary movement and up and down traverse by the bobbin.

2. In combination with the associated spindle, bobbin and flyer of a roving frame, a cleaning device for the flyer freely mounted upon the spindle, said cleaning device having rotary movement and up and down traverse by the bobbin,

said cleaning device being positioned upon the spindle above the bobbin and having close contact with the upper end of the bobbin.

3. A clearer device for the flyer of a roving frame comprising a member having its central portion constructed and arranged to allow said member to be freely mounted upon a spindle of the roving frame above the bobbin thereon for both rotary movement around the spindle and up and down traverse between the arms of the flyer, and brushing elements carried by the member for contact with the fiyer.

4. A clearer device for the flyer of a roving frame' comprising a member having its central portion constructed and arranged to allow said member to be freely mounted upon a spindle of the roving frame above the bobbin thereon for both rotary movement around the spindle and up and' down traverse between the arms of the flyer, and brushing elements carried by and extending outwardly beyond the ends of the member.

5. A clearer device for the fiyer of a roving frame comprising a member having its central portion constructed and arranged to allow said member to be freely mounted upon a spindle of the roving frame above the bobbin thereon for both rotary movement around the spindle and up and down traverse between the arms of the fiyer, and brushing elements carried by and extending outwardly beyond the ends of the memher and upwardly from the intermediate portion of the member.-

6. In combination with a bobbin and fiyer of a roving frame, means for cleaning the flyer rotated by and having up and down traverse with the bobbin.

roving frame, means rotated and traversed up and down by the bobbin for cleaning the flyer, said means being between the arms of the fiyer.

8. Means for cleaning the flyer of a roving frame comprising an element mounted for both rotary movement and up and down traverse, and means for transmitting such rotary movement and up and down traverse to the element.

9. Means for cleaning the flyer of a roving frame comprising an element mounted for both rotary movement and up and down traverse, and means for transmitting such rotary movement and up and down traverse to the element, said means constituting a bobbin with which the fiyer is associated.

10. Means for cleaning a flyer and a mounting for said means so constructed and arranged to allow said means to rotate and to have up and down traverse independently of the flyer.
